[Xymon] Help tracking down ghost client

[Root, Paul T]

This generally means that the xymon server is still performing a test on this address.

Do you have any ext scripts or maybe cron scripts that still are running to look at this machine.

What I generally do is add the machine back into the hosts.cfg file so it will show up and tell me what test is the issue. Fix that and remove the host again.

Subject: [Xymon] Help tracking down ghost client

Xymon 4.3.17 on Oracle Linux 6
I have a ghost showing up on the my "Ghost Clients" report and I can't figure out what's is happening.  A quick search of the archive didn't turn up anything similar.
On the Ghost Client report:
Hostname              Sent from    Candidate            Report age
mail07.example.com<http://mail07.example.com>    10.10.1.2    xymon.example.com<http://xymon.example.com>    0:32

This "mail07" [g]hostname doesn't exist in my hosts.cfg.  It was removed when the host was decommissioned two months ago.

The "sent from" address is my Xymon server.  The "report age" counts up to just over 3 minutes, resets to 0, and starts incrementing again.
This [g]host was a net-only testing host -- CONN, SMTP, and HTTP. There are references to the [g]hostname in analysis.cfg and alerts.cfg but those shouldn't cause this.  The "mail07" string does occur in the ~/server/tmp/xymond.chk file but it seems to be ghost report.  The xymond.chk line ends in "nGhost reports:\n  10.10.1.2      reported host mail07.example.com<http://mail07.example.com>\n|||0|0". No other file in ~/server/etc contains "mail07".
I added "--debug" to the xymonnet's CMD line and to the ~/server/ext/xymonnet-again.sh but "mail07" doesn't show up in either log.

Any thoughts on where to look next?
Thanks.
